## Function Documentation

Bool dmxBEFreeFont | ( | ScreenPtr | pScreen,
|  | FontPtr | pFont
| ) |  |

Free pFont on the back-end associated with pScreen.

References _DMXScreenInfo::beDisplay, dmxFontPrivateIndex, dmxScreens, and _dmxFontPriv::font.

Referenced by dmxBEDestroyResources(), and dmxUnrealizeFont().

Bool dmxBELoadFont | ( | ScreenPtr | pScreen,
|  | FontPtr | pFont
| ) |  |

Load the font, pFont, on the back-end server associated with pScreen. When a font is loaded, the font path on back-end server is first initialized to that specified on the command line with the -fontpath options, and then the font is loaded.

References dmxDebug, and dmxLog().

Referenced by dmxBELoadFont(), and dmxSetFontPath().

void dmxInitFonts | ( | void |  | ) |

Initialize font support. In addition to the screen function call pointers, DMX also hooks in at the ProcVector[] level. Here the old ProcVector function pointers are saved and the new ProcVector function pointers are initialized.

References dmxProcSetFontPath(), and dmxSaveProcVector.

Bool dmxRealizeFont | ( | ScreenPtr | pScreen,
|  | FontPtr | pFont
| ) |  |

Realize the font, pFont, on the back-end server associated with pScreen.

References _DMXScreenInfo::beDisplay, dmxBELoadFont(), dmxFontPrivateIndex, dmxScreens, _dmxFontPriv::font, and _dmxFontPriv::refcnt.

void dmxResetFonts | ( | void |  | ) |

Reset font support by restoring the original ProcVector function pointers.

References dmxSaveProcVector.

static int dmxSetFontPath | ( | DMXScreenInfo * | dmxScreen | ) | `[static]`

Bool dmxUnrealizeFont | ( | ScreenPtr | pScreen,
|  | FontPtr | pFont
| ) |  |

Unrealize the font, pFont, on the back-end server associated with pScreen.
